Question

metodo de igualacion 3x+ 2y= 8 4x-3y=5

Answer 1

Explicación paso a paso:

$3x + 2y = 8 \\ 4x - 3y = 5$

$\times 4(3x + 2y) = 8 \\ \\ \times 3(4x - 3y = 5$

$12x + 8y = 32 \\ 12x - 9y = 15$

$- 1y = 17 \\ y = \frac{17}{ - 1} \\ y = - 17$

$3x + 2( - 17) = 8 \\ 3x + ( - 37) = 8 \\ 3x - 37 = 8 \\ 3x = 37 + 8 \\ 3x = 45 \\ x = \frac{45}{3} \\ x = 15$
